SmartKeyer

I made this keyer for my own use when I found my old paddle from 30 years ago. It interfaces to a standard PC PS2 keyboard.

Below is the prototype in a small case. The LCD can be bought for around $12. Apart from the PIC Micro the only components are a
crystal, a few resistors, caps, two transistors and a couple of switches. If you don't plan to use it without the keyboard then you don’t
need the switches.

If a few people are interested I may see about getting some PCB’s made but for now I have a
board layout, PCB mask and a circuit if anyone is interested in making one.

The unit has a 100 char buffer for the keyboard. Any buffered chars or prerecorded message
can be interrupted by pressing the ESC key or by touching the paddle. You can start a
prerecorded message and immediately start typing to continue on from the message end.

I would love feedback from a serious CW ham and a wish list for changes and features that
he/she would like and I will try to make the changes and improve the unit.
